Natsu's first training is Natala he is a Naginata weapon user. He trains him by putting a heavy armor chest piece for him to wear while telling him to try his best to hit him. Wearing this is almost impossible for a child to move don't talk about moving a weapon to attack but he tries his best and can only swing 5 strikes before exhausting himself. Katsu makes some sandwiches for them to eat while resting to recover their energy.

Next is Kylie he is a Dual wield sword weapon user so he makes him wear a blindfold and throw eggs into him this training helps him react to ambush attacks. For the first time to receive this training, almost all the eggs hit his face when he manages to block one egg Katsu immediately changes his throwing position making it harder for him. When their training is done Kylie's body is completely bath in eggs luckily for him they are near a lake for him to wash.

For Remus, she is a sword user he didn't start with training swordsmanship. He gives her a simple task is running around the lake this may be simple but the moment she got distracted he will flint her head and make her repeat until she stops getting distracted and run full 10 laps.

Balluck training is different from the rest Black magician girl personally train her to learn magic, she is not talented in any kind of weapon but Black magician girl did she some potential in her and accept as her first apprentice. Different from the last training she gives to Esdeath, Katsu, and Leone by accepting her, Balluck can be called the next Black magician girl she can learn spells directly from her and can learn spells from her book but because the book is bound to Black magician girl Balluck have to write it down by hand and Black magician girl will help her understand.

Gin training is improving her skill in using a large butcher sword and training her hand to hand combat but Gin can only use that weapon in real enemies if sparing she has to use her hand as not to hurt her friend by accident

Najasho is a sword user and lazy bastard so Katsu gives him just a simple task slash his sword until he is exhausted. Any kind of laziness that appears in his practice he will simply receive a fist of love in the head.

Pony likes to fight by hand so he gives her the same treatment as Leone by giving her the same fighting technique and let them fight with each other to gain experience since he is way out of hand for her to practice.

A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

Guy already has superhuman levels of physical strength, speed, stamina, and endurance for a child, and his hand to hand combat are good enough but his pervert trait is too much even for a child so with the help of Black magic girl she creates illusions of ugly girls for him every time he thinks something pervert and since that day he becomes traumatized but Katsu believe he will live though

Cornelia is also a person who likes to fight with her fist but her way of fighting is less aggressive than Leone and Pony her attack is more proper and well organized every attack is aimed at vital points exhausting the opponent making them have to fight in a defense position. He practices her by teaching her to parry, he holds a wooden sword while Cornelia wears gauntlets to protect her hand since he doesn't want to hurt her his attack is only fast there isn't too much force so she parries it but this is practice so he increases the difficulty every time she succeeds.

Tsukushi a firearm user but since a sniper is hard to come by so she just use a pistol instead, her Marksmanship is very good, and possesses high-level eyesight but when lost her gun she becomes defenseless so he teaches her some military combat with a hand knife and practices her shotting by throwing rocks for her to aim at.

Womyn is a katana user since the technique that he learns from the card is all about killing an opponent quickly so he can only teach her that. Her training is increasing her drawing sword speed by putting heavy gauntlets onto her hands and let her strike a tree with all her might. He has to admit she is determined to become stronger but her talent is too poor so he teaches a hidden trick

Green likes to use a whip(kinky) but Katsu doesn't have any knowledge to teach him about using it so he can only learn it himself instead he teaches him hand to hand combat and knife fighting since he seems intelligent Katsu also teaches him how to make a smoke bomb, poison and hidden weapon.

Akame and Kurome are the most special. He trains them by giving them techniques that help instant kill opponent if fast enough, holding sweets in his hand and give them a condition that if they manage to hit him once they can receive the reward. The two sword users like hungry wolf pounce at him nonstop even if their sword skills are not good their determination helps them become stronger. In the end, even though they didn't manage to get a hit on him he still gives them sweets.

Leone and Esdeath training is practicing their technique, he already teaches everything he can they now only need to perfect it and increase their strength.

Of course, he didn't neglect his training with Dark magician girl enchant she makes the gravity around him increase by two times. Despite the difficulty in having this weight on him while training the children he still manages to pull through the whole day he even tells her to keep it permanently if he is not in combat to help his body to adapt.

After an exhausting day, he makes dinner and finally lies on the soft bed with a few accompany him.
